5 Referring to the distance to the subject, press the SB-24 M

button until the SB-24'sdistance scale indicates a distance which corresponds to the actual focused distance to the subject. Now, the SB-24'sLCD (lower right corner) will indicate the level of flash power needed to provide a flash exposure equal to the daylight exposure.

However, as previously noted, in order to get a good fill-flash ratio, the flash exposure should be one to two stops darker than the daylight exposure. Therefore, press the M button one or two times more. This will adjust the flash to one or two levels less light. (i.e. half the power which will reduce the exposure by one f/stop . Pressing it twice moves it to 1/4, which is two stops less than full (111) power.)

It is possible to approach this procedure from another point of view; that is by first adjusting the flash to the desired flash power setting, then selecting a lens aperture which is one stop smaller than that indicated by the flash, and then adjusting the shutter control for the correct available-light exposure.

Whichever method you use, you will need to make a creative decision by chOOSing the fill-flash ratio. We hasten to note that while you may wish to use the manual mode, when using the SB-24 with Matrix Balanced Fill-Flash, all of these steps are accomplished automatically.
